单用~(99m)Tc-焦磷酸盐(PPi)心肌梗塞(MI)显像的结果常难以与心脏外组织摄取或伪差鉴别。本文采用~(99m)Tc-PPi和~(201)Tl两种核素同时作两种不同能量射线的SPE-CT,来诊断急性右室心肌梗塞(RVMI)。共检查190例急性MI病人,男146例,女44例,平均年龄37～90岁。在胸痛开始后6小时内入院者,都作急诊冠状动脉造影,若有冠状动脉阻塞,即注射尿激酶入冠状动脉或作
Results of myocardial infarction (MI) imaging with ~ (99m) Tc-pyrophosphate (PPi) alone are often difficult to identify with extracardiac tissue uptake or artifacts. In this paper, SPE-CT with two different energy rays, 99m Tc-PPi and ~ (201) Tl, was used to diagnose acute right ventricular myocardial infarction (RVMI). A total of 190 cases of acute MI were examined, 146 males and 44 females, with an average age of 37 to 90 years. In 6 hours after the onset of chest pain admission, are for emergency coronary angiography, if there is coronary artery obstruction, that is, injection of urokinase into the coronary artery or for
